If you’re the type of person who enjoys/has a work-related need to track airplanes using their iPhone or iPad, you may want to download plane-tracking app Plane Finder, which has just received a brand new update — letting you watch previous flights, dating all the way back to April 2011.

The app lets you replay holiday flights, diversions, and major incidents, as well as easily seeing the effect of storms, ATC strikes, volcanic ash clouds, and more.
